Underfloor Heating Repair & Servicing in Alton
Repair and servicing

Planned maintenance keeps warranties valid and catches seized actuators and failing pumps before they turn into a cold winter weekend.
Fault Finding & Diagnostics
Underfloor heating not working
If your underfloor heating has stopped working, is not getting hot, runs cold or heats unevenly, we diagnose the actual cause — no parts swapped on guesswork.
One zone not working
A single cold zone normally traces to an actuator that has not lifted, an unbalanced or closed flow meter, an airlock in that loop or a thermostat not calling for heat. Thermal imaging shows us which loop is dead before anything is lifted.
Wet System Repairs
Wet, water-fed and hydronic underfloor heating repairs: loop isolation, circuit re-balancing, blockage clearance and pipe repairs — carried out with the smallest possible opening in the floor finish.
Manifold Work
Manifold repair and replacement
Leaking, corroded or undersized manifolds repaired or replaced, including isolation valves and new zone bars.
Actuators, flow meters and pumps
Actuator replacement where an actuator is not working, flow meter replacement, manifold balancing, and circulating pump replacement when the pump is noisy, seized or not running.
Controls
Mixing valve replacement, blending valve repair, wiring centre repair or replacement, and thermostat replacement when a stat is not working — including Heatmiser wiring centres and thermostats, plus other common wired and wireless control brands.
System Issues
Airlock removal, system flushing and powerflushing, chemical inhibitor dosing, leak detection, pipe repair and pressure-loss investigation — the faults that quietly kill output before the system fails outright.

FAQs about Underfloor Heating Repair in Alton
My underfloor heating is not getting hot — what is the likely fault?+
The most common causes are a failed actuator, a seized zone valve, an airlock in a loop, a faulty thermostat or wiring centre, or a mixing valve stuck at the wrong blend temperature. Our engineer diagnoses the actual cause on site rather than replacing parts on guesswork.
One zone is cold but the others work — can you fix that?+
Yes. A single cold zone usually points to an actuator that has not lifted, a closed or unbalanced flow meter on the manifold, an airlock in that loop, or a thermostat that is not calling for heat. We isolate the loop, flush it if needed and rebalance the manifold.
Do you offer emergency underfloor heating repair in Alton?+
Yes — we offer same-day emergency attendance across Alton for total heating failure, leaks and pressure loss. Call us and we'll confirm the earliest slot.
Can you find a leak without lifting the whole floor?+
Usually. We use thermal imaging, pressure testing and acoustic leak detection to pinpoint the failure, so any floor opening is kept to a small, targeted area before the pipe is repaired and the system refilled.
Do you service underfloor heating as well as repair it?+
Yes. Annual servicing covers manifold inspection, actuator checks, flow-meter rebalancing, inhibitor testing, pressure checks and control/thermostat testing — the work that prevents most breakdowns in the first place.
